Answer:

\sqrt{45}

Solve for w.<br><br> −(1/4w 8) 8=3<br><br> w=52w=52<br> w=134w=134<br> w=−34w=−34<br> w=−12
prohojiy [21]
-(1/4 w + 8) + 8 = 3
-1/4 w - 8 = 3 - 8 = -5
1/4w = -8 + 5 = -3
w = 4 x -3 = -12
w = -12

A salesperson is paid a weekly salary of $1000, plus a commission of 5% of all her sales for the week.
garri49 [273]

Answer:

A) Total weekly salary = $1000 + ( 0.05 × s )

B) Yes this is a function

C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.

D) Domain will be [ 0, ∞ ]

Step-by-step explanation:

Given :

Weekly salary = $1000

Commission = 5% of all her sales

Let the number of sales be 's'

thus,

A) Total weekly salary = $1000 + ( 0.05 × s )

B) Yes this is a function

C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.

D) The domain here will be all the possible values of sales i.e 's'

Hence,

sales will always be positive

thus,

domain will be [ 0, ∞ ]
